Leaders and negotiators from more than 190 countries are converging on Paris from Nov. 30 to Dec. 10, 2015 for the UN climate summit, known as COP21. The international talks will focus on how to slow global warming and reduce greenhouse gas emissions.

Prime Minister Justin Trudeau is in Paris for the climate talks. Joining him is a Canadian delegation including many premiers and a representative from every province and territory--and Elizabeth May, leader of the Green Party of Canada, who is featured on this week's program.

At the same time, around the world, people are urging world leaders to take this opportunity to hammer out a workable agreement. Climate change advocates have been holding events as part of Global Climate Marches. Organizers say there are over 2,000 of these marches-- which make it one of the largest climate change protests in history. In Paris itself, there are many protests--including one by the Place de la Republique that turned ugly. Riot police used tear gas to break up that demonstration and about a hundred people were arrested.

On this week's program we heard what you're thinking about on the push to respond to climate change not just internationally-- but also here in Canada.

What changes would you like to see industry making? What changes are you prepared to make for climate change? And how much are you prepared to pay for the cost of a greener economy? Are you worried about the economic cost of climate change?

Our question: "What are your expectations for the climate change summit in Paris?"
